【 摘 要 】
A search for physics beyond the Standard Model (SM) is performed using a final state with multi-muons and collision data collected by the Compact Muon Solenoid (CMS) experiment at the CERN Large Hadron Collider (LHC). The topology under study considers events with pairs of oppositely charged muons (dimuons) with a low invariant mass and a common origin. This selection offers an extremely low contribution from SM processes and fits into several beyond the SM signatures. Results are interpreted in a model-independent fashion and in the context of two scenarios: Supersymmetry including "dark" sectors (dark-SUSY) and Next-to-Minimal Supersymmetric Standard Model (NMSSM). Both scenarios postulate a non-SM decay of the Higgs boson to a pair of new light bosons which subsequently decay to a pair of muons. In the case of the dark-SUSY scenario, the hypothetical production of dark photons could give an insight on the origin of dark matter.
